Wall Lake is important for migration
Wall Lake is a staging area (location where migrating birds stop to rest and feed) for many birds, including the Bufflehead Duck. This is why we see so many migrating waterfowl on Wall Lake in the spring and fall.
Why the name Bufflehead?
The Bufflehead Duck gets its name from a combination of "buffalo" and "head", due to its large head.
Their overall small size has evolved to fit the nesting niche of small tree cavities. The small body size gives them abundant energy and playfulness and they are a delight to watch.
Bufflehead Ducks nest primarily in holes in trees made by other birds, mainly Flickers. Over the decades, loss of forestland has reduced nesting habitat and has reduced Bufflehead populations. They summer in Canada and winter in the southern USA, seeking open water.
Bufflehead Ducks forage underwater and in freshwater eat insects, snails, fish eggs, and small amounts of plants. Wall Lake is an important source of food for migrating waterfowl.
In saltwater Buffleheads eat primarily crustaceans and mollusks.
